The term "sensorimotor" refers to the integration of sensory experiences and motor actions. It describes how our senses, like sight and touch, help us understand the world around us and guide our movements. For example, when a baby reaches for a toy, they use their sight to locate it and their muscles to grasp it, combining sensory input with motor output. In developmental psychology, the sensorimotor stage is a key phase in which infants learn through their senses and actions. This stage, identified by Jean Piaget, lasts from birth to about two years old, during which children explore their environment, develop coordination, and begin to understand object permanence.
